In order to minimize the side effects and allow a smaller number of punctures and amount of anesthetic solution used for control the pain in the maxilla, Friedman & Hochman (1998) described the anterior middle superior alveolar anesthetic technique (AMSA), for various dental procedures in the jaw. The AMSA has the ability to not anesthetize, undesirably, other anatomical structures beyond the periodontium and teeth such as upper lip, bridge of the nose and lower eyelid. This advantage occurs due to the fact that the anesthetic solution is administrated in a small location on the palate where it is not able to reach the sensory fibers of the lips and face and, therefore, does not alter the activity of the muscles that deal with facial expressions. In addition, the administration of only 0.6 to 0.9 ml of anesthetic, is able to induce anesthesia of the pulpal and soft tissues of the palate region. This is a significantly smaller amount of anesthetic than what is usually administered for the desired analgesia for dental and periodontal structures.
